Hop Up Units for CQR MOD

I have a CQR MOD 1 and will be getting a tightbore barrel, with this I was considering a new hop up unit. I'm slightly new when it comes to internals. I am not sure if there are any specific types that would work best with my gun.

I know of no aftermarket hop-up units that will provide any better results. No need to worry there.

From personal experience, the kwa stock barrel is fine. I tried an airsoft gi tbb (m16 length with a suppressor) in my cqr mod 1, and the range was the same. Probably cause i need to get a new cylinder
